This APAR introduces the OSPROTECT system parameter which specifies the operating system protection mode for unauthorized programs and users. With this apar applied, software must no longer reference the IHAPSA field PSASTAK because the PSASTAK is no longer the beginning of the normal FRR stack. PSACSTK is an existing pointer to the beginning of the normal FRR stack. Software that references PSASTAK must be converted to use PSACSTK as the pointer to the normal FRR stack.The PSASTAK is related to recovery management and the apar itself changes the definintion of the PSASTAK field in module IHAPSA to PSACSTK and software continuing to reference PSASTAK can receive a S0C4.
